Forecasting Summer 2025

The end of May officially kicks off the summer season and all the celebratory get togethers, parties, events, and vacations. While advancements in technology have provided many ways to check the weather conditions usually weather apps are limited to an approximately 10-day forecast. If you are looking for longer term forecasts for the entire summer season, one place to turn is the Old Farmer’s Almanac first published in 1792 and founded by Robert B. Thomas. Farmers once consulted the book as a main source of guidance for upcoming planting seasons.

The Almanac relies on a “secret formula” that has remained concealed for over two hundred years, but likely incorporates studying the sun, moon, and planetary positions as well as historical weather patterns and tidal records, and aspects of solar science, climatology, and meteorology. While the Almanac itself has consistently claimed an 80% accuracy rate, other studies like one out of the University of Illinois by Professor Emeritus John Walsh in the Department of Atmospheric Sciences, have found a much lower rate closer to 50 percent accuracy in comparing the Almanac’s monthly temperatures and precipitation forecasts to actual weather data over a five-year period.

According to the predictions of the Almanac this year Summer 2025 is going to be hot, rainy, wet, and humid across the Northeast. After what has seemed like an extremely wet spring already, this may not be a prediction many want to accept. However, the Almanac, contains content other than weather predictions including puzzles, recipes, holiday traditions, and even a word of the day on the website. You can find the Almanac online and ways to order and locations to buy a print copy at www.almanac.com.
